LED bulbs incorporating negative Poisson's ratio structures

Abstract

An LED bulb includes a bulb body, with a first set of components composed of an NPR material, and a second set of components composed of a PPR material. The first set of components include thermal encapsulants, thermal pottants, a heat sink, thermal interface materials, and LED chip encapsulants. The second set of components include a socket, a base, an LED driver, conformal coating, adhesives, reflector materials, an LED module, LEDs, primary optics, and secondary optics. The incorporation of NPR materials into LED bulb components can provide various advantages over LED bulbs that include only positive Poisson's ratio (PPR) materials. For example, NPR materials can facilitate improved heat dissipation from, and/or cooling of, integrated components of LED bulbs, among other benefits.
